You must install first the component and then second the language pack for that component Here are a example how to install wmi dism /image:C:\winpe_x86\mount /Add-Package /PackagePath:"C:\Program Files\<version>\Tools\PETools\x86\WinPE_FPs\winpe-wmi.cab" dism /image:C:\winpe_x86\mount /Add-Package /PackagePath:"C:\Program Files\<version>\Tools\PETools\x86\WinPE_FPs\en-us\winpe-wmi_en-us.cab" so the package WINPE-HTA_SV-SE.cab is only the language pack.
